摘要 |
<p>The injector i.e. common rail injector (1), has a control valve (12) with a valve casing (16) enclosing a guide bolt (25). A fuel discharge channel (10) from a control chamber (7) is blocked and released by the control valve. The pressure in the chamber is controllable in such a manner that a nozzle needle (3) connected with the chamber is adjustable between an opening position and a closed position. A valve seat (22) is designed as flat seat with an even valve seat surface, and the casing rests on the even seat surface with a front-sided circulating edge when the control valve is closed.</p> |
